I use the "Poser model as reference" approach too. I model in Max, but I just make the model there so that it looks right. Sometimes I work to scale, but mostly just the "this looks right". Then I import it into Poser and scale it THERE untill it "looks right" again, compared to V3 or something. I then export the obj and when you re-import it with ALL boxes unchecked (also export it with everything unchecked) it comes in, at 100% and in the right size.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
